I've been working my way through Bron/Broen/The Bridge. This TV show is a joint production from Denmark and Sweden. I'm enjoying it, but my family thinks it's foreign.
Saga is a Swedish police officer in Malmo. Martin is a Danish police officer in Copenhagen, right across the bridge that joins the two countries. When a body is discovered mutilated right on the international border, the two must work together. When Martin is introduced to the Swedish police department, one of Saga's co-workers asks in an aside "Should someone tell him that Saga is... a bit odd?" I remember the response as "I think he'll work that out." Saga is probably on the autism spectrum, albeit movie autism. She's monomanical about police work, bad at relationships, denies emotions, and is blunt and abrupt to the point of rudeness. Martin is a womanizer and somewhat disheveled, willing to bend rules to achieve goals. His character reminds me of Columbo, but perhaps without Peter Falk's inherent coolness.
After working through their personal friction, they form a good team, complimenting each other's strengths. It has a US/Mexican remake. I made it 5 minutes before deciding that the plot was perfectly lifted from the original but the actors aren't nearly as good.
